00:01
Okay, we have this circuit.
00:02
We want to calculate a few things.
00:06
So i'm going to recognize that this pair of capacitors, they are in parallel.
00:15
So their equivalent is two plus three.
00:24
All right.
00:24
And then we'll come down here and redraw the circuit.
00:32
So it looks like this.
00:35
So the c equivalent, one.
00:39
These now we've got three capacitors in series.
00:58
The common denominator here is 10.
01:02
That's actually, there's our c equivalent, is two microfaradts.
01:19
Okay.
01:23
So we want to figure out the charge.
01:29
We'll see, here's how we're going to do that.
01:31
So we basically have, if we think of the equivalent capacitor, is a two microferral capacitor.
01:38
So i'm going to calculate, a charge, which i'll call q equivalent, which is the charge on the equivalent capacitor, is equal to cv.
01:55
So that's, all right.
02:14
And if i go and number the capacitors, this is what i want to do.
02:19
So this is one, two, three, and four.
02:27
Now i'm going to come down to this circuit.
02:29
So this was three and four...
